According to Griess reaction, diazonium-salts formed from aromatic amines such as sulfonamides etc., react with NaNO_2 in acid medium and may be coupled with α-naphthylamine or diphenylamine to produce red colored compounds.

一按Griess反应芳香族胺类的重氮化鹽，如对氨基苯磺醯胺类药物等，在酸性溶液中皆能与α-萘胺或二苯胺分别偶合成偶氮色素而显紅色，过多之亞硝酸可与氮色素再作用使紅色消失而呈棕黄色。

The baseline separation of 9 neutral compounds (thiourea, benzene, toluene, ethyl benzene, n-propylbenzene, naphthalene, n-butylbenzene, fluorene and anthracene) and 7 acidic, basic and neutral compounds (thiourea, o-aminophenol, phenol, benzene, o-methylaniline,α-naphthylamine, 2,4-dichloroaniline) can be obtained under optimized capillary electrochromatographic conditions.

在该均相硅胶基质整体柱上成功地分离了9种中性物质(硫脲、苯、甲苯、乙基苯、正丙苯、萘、正丁基苯、芴和蒽)以及7种中性、酸性和碱性物质(硫脲、邻氨基酚、苯酚、苯、邻甲苯胺、α-萘胺和2，4-二氯苯胺)。

It is reported in this paper that diphenylcarbazone reacts with Hg in pH 2.2 in the presence of Tween─60 to form a purple complex with its absorption maximum at 486 nm. The existence of chloride will depress the absorption of the complex. The negative absorption will be proportional to the consistence of chloride.

摘要﹞ 在pH为2.2的酸性介质中，在吐温－60溶液的存在下，Hg与二苯卡巴形成紫色的配合物，其最大吸收波长为486 nm，氯离子的存在可使原紫色配合物吸光度降低，其负吸光度与氯离子浓度成正比。

Factors including pH, concentrations of heavy metals, dosages of minerals, ionic strength and temperature were studied and the results indicated that nepheline syenite and olivine had significantly higher capacity of absorbing heavy metal ions than glacimarine clay since they possessed stronger neutralization ability to acidic solution.

考察的因素包括溶液pH值、重金属离子浓度、矿物用量、离子强度、温度等，并得出结论，霞石正长岩和橄榄石吸附重金属离子的能力明显强于冰海粘土。通过理论分析表明，导致这一现象的原因为霞石正长岩和橄榄石对酸性溶液具有更强的中和能力。

Objective: To investigate the nephrotoxicity of plumbagin on human embryonic kidney cell 293 in vitro and protective effects of acid fibroblast growth factor on the cells.

目的：观察白花丹素在体外对人胚肾细胞293的毒性，以及酸性成纤维细胞生长因子对白花丹素所致肾损伤的保护作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
